Planet Earth

The idea of a round Earth appears to have originated in Greek Philosophy. Aristotle provided the first evidence of a round Earth, noting that explorers traveling south saw southern constellations rise higher above the horizon and that Earth cast a round shadow on the moon. Eratosthenes used the angle of sunlight at different latitudes to estimate Earth's circumference with surprising accuracy.

yes it is the world may look round but it is actually pear shaped

coal, metal and gemstones are the main 3 things found in the Earth's crust.

Earth is sometimes called the "Grand Oasis" because it is one of the few planets in our solar system known to have liquid water on its surface, making it a haven for life as we know it. This abundance of water and life-supporting conditions makes Earth a precious and unique oasis in the vastness of space.

The sun will appear about 160 times smaller from Uranus compared to Earth due to the greater distance between Uranus and the sun. This is because Uranus is much further away from the sun than Earth is.

1. Venus is similar in size and mass to Earth, making them roughly "sister planets" in terms of their physical characteristics.
2. Both Venus and Earth are rocky planets with similar compositions and densities.
3. They are relatively close to each other in the solar system, with Venus being the closest planet to Earth.

Yes, the Earth's tilt is the main reason for the seasons. As the Earth orbits around the Sun, its tilt causes different parts of the planet to receive varying amounts of sunlight throughout the year, resulting in the distinct seasons of spring, summer, autumn, and winter.

When the earth is referred to as an isolated planet, it usually means that the earth is distinct from other celestial bodies in terms of its environment and characteristics. This isolation highlights the uniqueness of the earth in terms of its ability to support life and its position in the universe.

The Earth is unique in many ways. It has an atmosphere unlike most planets as well as water. water has never been proven to be on any other planet except earth, we can only speculate. these two facts make the Earth one of a kind.

No, silicon is not found in the Earth's core. The Earth's core is primarily composed of iron and nickel. Silicon is mainly found in the Earth's crust and mantle.

The present pattern of tides is the result of gravitational forces between the Earth
and both the sun and the moon. If the moon disappeared but the sun remained,
there would still be two high tides and two low ones every day. They would be more
consistent in amplitude but lower on the average than they are now. Also, the highs
and lows in any one place would always occur at the same time of day ... the whole
pattern would not creep later by 45 to 50 minutes per day as it does now .

Yes, you can see moving planets from Earth. Planets like Venus, Mars, Jupiter, and Saturn are visible in the night sky and appear to move relative to the stars due to their orbits around the sun. With a telescope or even the naked eye, you can observe their movement over time.

Earth is considered a temperate planet because it has a relatively stable and mild climate compared to other planets in our solar system. This is due to its distance from the sun, which allows for the presence of liquid water, moderate temperatures, and a balanced greenhouse effect. Earth's atmosphere also plays a crucial role in regulating its temperature, making it suitable for supporting life as we know it.

Mining occurs in the Earth's crust, which is the outermost layer of the Earth. Most mineral resources that are mined for industrial purposes are found within the crust, though some mining activities may extend into the upper part of the mantle.

Earth is often referred to as the unique planet because it is the only known planet in the universe to have liquid water on its surface, which is essential for life as we know it. Additionally, Earth has a diverse range of ecosystems and abundant biodiversity, making it a truly exceptional and habitable place in the solar system.

The element that helps create Earth's magnetic field is iron. Iron is present in the Earth's core and its movement generates the planet's magnetic field through a process known as the geodynamo.

No, Earth is not far away from itself. Earth is the planet we live on, so it is always present beneath our feet.

no...

Mercury's diameter is 38.3% of Earth's diameter, its volume is 5.6% of Earth's volume, and its mass is 5.5% of Earth's mass.

When the Earth rotates during the day, half of it will be pointing to the sun which creates morning. When it rotates away from the sun, it creates nightfall. This is why Japan is at least 12 hours behind from Montreal. When it's morning there, it's nightime here.

No. Unless unless you are a 1200 pound women then you have your gravitational pull

Eccentricities:

Mercury 0.206

Venus 0.007

Earth 0.017

Mars 0.093

Jupiter 0.048

Saturn 0.056

Uranus 0.047

Neptune 0.009

Pluto 0.250

Only Venus and Neptune have less eccentric orbits than the Earth.

The planet's orbits is nearly a circle, with the Sun off-centre by a distance equal to the radius times the eccentricity.

The minor axis is equal to the major axis times sqrt(1 - eccentricity-squared).

For all of Earth's water to evaporate and remain as vapor, temperatures would need to exceed 100 degrees Celsius (212 degrees Fahrenheit) to reach the boiling point of water. Once water evaporates into vapor, it would continue to expand and dissipate into the atmosphere.

That question can not be answered. The closes answer is more than 3/4's of the world is water.
